I started building my first computer. The graphics card requires 2x 8pin power connectors. If I use 2 Vga cords I get no picture and the monitor stays black. If I use my pci-e with a 8pin and 6 pin. I get a picture. If I use the pcie and the vga I get no picture. I don’t want to use the just the pcie because I don’t want to risk anything because I’m missing 2 pins. Why does this happen? What could I do? Should I just use the pci-e? Note: the graphics card does light up.
